Definition of unction in English:

noun

Following the designation process, Halpern and Long see an underlying mythos that ritual unction ought to be followed by a battle in which the designated individual demonstrates his worthiness to rule.

Exorcisms were performed particularly on those items employed in unction and on holy water, as well as food and drink.

Here I would suggest that one of the main secrets of success in the early Church lay in the fact that the early believers believed in unction from on high and not entertainment from men.

Origin

This is from Latin unctio, from unguere ‘anoint’, also the source of unguent (Late Middle English), and via French of anoint (Middle English) and ointment (Middle English). The phrase extreme unction in the Roman Catholic Church refers to a final anointing of a sick person in danger of death. Unctuous had the early sense ‘greasy; like an ointment’, which rapidly developed into ‘rich’. The sense ‘having spiritual unction’ developed in the mid 18th century, but rapidly developed the sense that this was hypocritical.
